i COMBINATION BRUSH.

Application filed July 26,

To all who/m t may concern:

Be it known that I, Gnonen 1V. STEuN, av

combination brush forming the subject mat-y ter of my (zo-pending application for .v S. Letters Patent filed April 17, 1924, Serial No. 707,083.

The principal objects of my invention are to generally improve upon and simplify the construction of the brush disclosed in my aforesaid application aswell as other forms of similar brushes; to provide relatively simple, strong and durable means whereby a brush having relatively soft ,flexible bristles of fiber, hair or the like, is mounted for sliding or pivotal movement upon the back of a brush having bristles of resilient metal or the like.

Brushes of the type'to which my invention relates are especially applicable for brushing and cleaning the surfaces of meat cutting blocks, tables and the like, and it is one of the objects of my invention to combine in a single implement two brushes having bristles of different materials and of different degrees of flexibility.

With the foregoing and other objects in view, my invention consists in the features i of construction and combination and ar- CIL rangement of parts hereinafter more fully described and claimed, reference-'being had to the accompanying drawings, in which Figure 1 is a top plan view of-a combination brush of my improved construction;

Figure 2 is an elevational view ofthe brush Figure B is an enlarged cross section taken approximately on the line 3-3 of Figure 1; l

Figure 4 is a cross section similar to Figure 3 and showing a modified arrangement for mounting the smaller brush upon the back of the brush yhaving the 'relatively heavy bristles;

Figure 5 is a detail section showing a modified form of sliding connection'between the brush backs;

Figure 6 is a plan view of a modified form of the brush in which-the relatively light 1924. serial no. 728,483.

brush is arranged for both sliding and pivotal movement upon the heavier brush;

Figure 7 is a plan View of a further modified form of the combination brush;

Figure 8 is a cross section similar to Figures 3 and 4, and showing a modified arrangement; of connecting the backs of the two brushes;

Figure 9 is a cross section similar to Figuresv 3 and 4, and showing a modilied arrangement of the pivotal connection between the two brush backs.

Referring by numerals-to the accompanyingdrawings, and particularly to the construction illustrated in Figures 1 to. 3, inclu.- sive, 10 designates a brush back, preferably of wood, having on one of its wider faces a field of bristles 11 of resilient metal. These metal bristles may be formed from narrow strips or bands of resilient sheet metal or they may be formed of wire cut into sections of proper length.

Overlying the upper surface of the brush back 10 and transversely disposed thereupon are plates 12, preferably :formed of sheet metal, the end 'portions 13 thereof being bent downward onto the side edges of the brush back and these downwardly bent ends are secured to the brush back in any suitable manner, but preferably by small nails kor screws, such as 14. Y Theplates 12 are provided with eentrally arranged slots 15, andI the material in said plates to the sides of said slots is elevated to provide narrow spaces 16 between said plates and the Vupper surface ofthe brush back 10.

These narrow spaces are formed for the reception of the heads 17 of rivets 18, which latter pass upwardA through a relatively narrow brush back 19 of wood or terial. Projecting from one side yface of this brush back 19 is a series ofrtufts of bristles 20 of relatively soft flexible material, such as fiber, hair orbroom straw. The upper ends of the rivets 18 project slightly beyond the upper surface of the b1 ush back 19, and said projecting ends are riveted into washers 21. Seated in tho under face of the end portions of brush back 19 are pins or studs having rounded heads 22, which latter are adapted to ride on the upper surface of brush back 10 whenbrush back 19vis moved transversely thereupon.

In the form of brush just described, the brush back 19 having the relatively soft bristles is mounted analogous maso as to slide freely across the brush back 10, and when moved to one edge thereof, as illustrated in Figures 1 and 3, the bristles carried by the brush back 19 project beyond the corresponding edge of brush back 10, thereby enabling the relatively soft bristles to be usedin brushing the surface of a meat cutting block or the like. l/ilhen brush baci: 19 is moved to a position adjacent to the Opposite edge or side or brush back 10 as shown by dotted lines in l5`igurek 3, `said brush baci: 19 and bristles 2O lie entirely within the space bounded 'by the edges of the brush back 10,

so that the latter may be manually engaged and readily manipulated so as to cause the free ends 'of the nre-tal bristles 1 the surface to be cleaned. g

V`'In Athe modified construction illustrated in Figure v21, the brush bacl: 19 carrying 'the :relatively soft bristles f2() is retained for sliding movement upon the heavier brush baci( 1'() by means of screws 23 that pass upwardly through lthe slots 15 in plates 12, the Ythreaded portions ot Ksaid screws being seated in brush back 19.

In the mo'dilied construction illustrated in Figure 5, the head fof a screw 2l that passes through the slot in plate 12 is enga-'ged in a washer 25, the latter being free to slide 1 to engage through the narrow space 176 between said plate 12 and the brush back 10,.

In the modified construction illustrated in Figure 6, a 'single slotted plate 12 is 'arranged transversely across the center of "brush "back 1'() andthe lighter brush back 19 is arranged to sli-de and pivot upon said slotted plate 121by means ot a rivet yor bolt such as 26. In this construct-ion. lthe relatively soft bristles carried by the brush bach 19 may project from .either side 4or the brush back 1'0, as shown by solid `and dotted lines in Figure G.

In the modilied con-struction illustrated in Figure 7, the lighter brush back 19 is connected to the heavier brush baci; 10 by means or a pin lor screw, such as 2i', and thus the lighter brush back 19 may be pivotally swung around from an 'out oi service position `on the heavier brush bafck 10, as shown by solid lines in Figure 7, to aposition for luse as illustrated by dotted lines in said ligure.

In Figure S the brush having the relative` ly solt bristles is pivotal-ly connected to a. strap 28 that 'extends 'transversely across the central portion of the heavier brush back 10, and thus the lighter brush may be pivotally swung' or reversed when shifted from one position to another.

In Figure 9, the brush back 29, having the soft liexible bristles, is pivotally mounted Aon abolt 30, the head of which is positioned beneath a transverse band 31 that is secured to the brush back having the steel or metal bristles.

Thus it will be seen that I have provided a relatively simple, practical and convenient combination brush wherein the relatively `narrow brush back carrying soft` flexible bristles is mounted for sliding or pivotal movement upon the back or a brushhaving relatively stili and 'heavy bristles yof metal or the like, thus producing in one convenient and readily handled structure an implement that can be advantageously used Ytor cleanin'g and scri'ibbing 'al-l surfaces. and particularly the surfaces of vmeat cutting blocks and tables.

lt will be readily understood that lvarious minor changes in the form, size and construction of my improved combination brush may be made without departing from the spirit of my invention, the scope of which is set Jforth in the appended claims.
